Dim Drive Light

[Super TWiT]

While I might test the power supply because I think I can manage that. I just read that you have been an electronics repair person for the last 30 years in another thread. That makes me look really bad! Please forgive my newbishness... I just don't want to break this thing.

So if I test the twelve volt pin, do I put both the positive and negative probes on the same pin?

It's all good! I don't mind helping out with the lighter stuff. And actually, I have a friend into Amiga now that's complained about some of these forums not being exactly "friendly" when it comes to questions. That a lot of Amiga people are kind of "snotty" that way compared to other computer enthusiasts. He's newly into Amiga and for the moment, he's avoiding subscribing to any forum for that reason. Hmm...  can't say I've ever noticed anything like that here.  lol

So, since you are willing to help with the light stuff, here's something REALLY light. If I want to test the 12 volt dc pin, should I put both the positive and negative probes on it at the same time?

 BTW, this is off topic, but I bought my multimeter cheap, and noticed in the manual that it takes a "9 volt transistor-type battery". I was upset until I realized thats just a regular 9 volt. Why in the world do they call it transistor type battery anyway?

Probably because it was a popular battery when transistor radios were hip.

[Super TWiT]

I guess. I thought of that too. It's not an old multimeter its digital, so I really have no idea.

[save2600]

LOL! Whoa, now that's going back. 9v batteries are still sometimes called that because they were popularly used, perhaps originally designed for use in most of the first truly portable handheld transistor radios. Little bit of trivia for 'ya!

And no.... you will never get a reading touching both DMM leads to one DC pin. Black to ground and Red to positive.... always. Ground, minus or negative is what you're looking for.

Well, plugged it had the red connected to pin 1 and the black to pin 2 as indicated on power brick, and I must have shorted something because I began to hear a high pitched ringing sound, so that's enough of that for now, atleast until I gather courage. LOL

[save2600]

Whaaat?     Well, there's a fuse inside of that supply - so hopefully that just needs to be replaced. Sorry man, but that was my very first cautionary rule - don't be shorting leads!!

[Super TWiT]

Maybe I didn't short anything. I just started hearing that noise so I shut it off. I double and tripple checked the pinouts.

[ElPolloDiabl]

If you want to test it safely get a set of leads that have crocodile clips on them. Have a crocodile clip and a probe plugged into the multimeter. Once you know which is the GND pin is put the crocodile clip on that. Then use the probe to touch the other pins. It won't slip around, so you won't short it.

[Super TWiT]

Yeah, I guess I should get a pair of those. I swear the leads weren't touching! Wow, now save2600 has abandoned me. LOL Is there a chance  I didn't short it? Well, off to home depot!

Oh He's back

Hey, a guys gotta eat you know! lol

Ummm... alligator clips are great, but I've found that unless you get some real small ones, you actually risk the chance of shorting a little easier in this case. Just my $.02.

So... did you plug it back in and retest?

BE CAREFUL!  =P

[Super TWiT]

No, not yet. I still am thinking about those clips. I probably need some anyway, so I will try to get the smallest size they have, and if they won't work well thats that. Come on now after my recent adventure you want ME to retest?

[save2600]

Alligator clips  are a good investment, so yeah - you'll need 'em sooner or later anyway. And don't test your power supply by plugging it into the Amiga after that high-pitched whine scare.  lmao

[Super TWiT]

I tested again and this time there was a louder noise than before. I KNOW nothing shorted this tims because I had some help holding the connector this time. I noticed a volt reading didn't register but that might be because it was only on a fraction of a second. So, maybe its time for the local electronics repair guy to take a look at this. There is a shop down the street. Where you serious about not plugging it into the amiga or was that where the lmao comes into play, because that would validate basic psu function.
